More than three years since Apple launched the App Store, Google is rumored to be on the verge of releasing a native iOS app for its Gmail service, according to a new report.

According to M.G. Siegler of parislemon, “multiple sources” have stated that the launch of the application is imminent.

“I believe it has already been submitted to Apple for review. If it gets approved, it should be out soon,” he wrote, adding that he believes it will get approved.

Siegler went on to note that tipsters have said the app looks “pretty fantastic…perhaps even surprisingly so.” A key feature of the app is expected to be the addition of push notifications for the popular email service. Other likely feature additions include Priority Inbox and one-click starring of messages, according to him.

The author also speculated that upcoming Gmail features such as “contact icons, better threading, deep searching functionality,” and even Google+ integration could make their way into the iOS application.

Despite the arrival of Apple’s App Store in 2008, Google has preferred to use a Web interface for Gmail on iOS. Apple’s native Mail app on iOS has included support for Gmail accounts for years, though it lacks a number of the features that Google offers via the Web app.

Numerous reasons have been put forth for the delay in a Gmail app. Originally, some suggested that Apple was blocking third-party mail apps to avoid confusion with its own Mail program as well as Google’s tendency to favor Web apps for its services. More recently, friction between Apple and Google over the Android operating system has been cited as another cause of the delay.

According to a recently released biography, late Apple co-founder Steve Jobs vowed to “destroy Android” after handset maker HTC released an Android smartphone that he felt stole his company’s innovations.

“I don’t want your money. If you offer me US$5 billion, I won’t want it. I’ve got plenty of money. I want you to stop using our ideas in Android, that’s all I want,” Jobs reportedly told Schmidt during a meeting in 2010.

While there may not be that many viruses out there for the Mac, there are still Trojan horse apps to make life a little bit harder.

Here’s another.

Per AppleInsider, a new Trojan horse hidden in a Mac OS X application can steal sensitive user data and take control of the computer’s GPU to generate Bitcoins, a form of currency used online.

In a report released on Saturday, security firm Sophos reported that DevilRobber, a Trojan horse that can steal sensitive user data, was found hidden inside copies of Graphic Converter 7.4 downloaded from bit-torrent file-sharing sites.

DevilRobber, also known as “OSX/Miner-D,” can steal usernames and passwords and is capable of spying on users by taking screenshots of their activity and sending the images online. In addition, the Trojan is able to run scripts that can copy information “regarding truecrypt data, Vidalia (TOR plugin for Firefox), your Safari browsing history, and .bash_history” to a dump.txt file.

The malware has also been found to search for “pthc” files, a term that is used to describe pre-teen hardcore pornography. It is not known at this time whether one of the secondary features of DevilRobber is to find traces of child abuse on affected computers.

Another unusual feature for the new Trojan is its capability of taking over a Mac’s GPU in order to generate Bitcoins, a digital currency that can be used to perform online instant payments without the oversight of a banking authority.

Users generate Bitcoins on personal computers after installing Bitcoin Miner, an application that’s compatible with Mac, Windows and Linux systems. Once obtained, Bitcoins are stored in the user’s digital wallet and can be used for future online payments. Bitcoins can also be exchanged for actual currency with the current exchange rate reportedly valuing one Bitcoin at US$3.20.

In addition to harnessing the power of the GPU to generate more Bitcoins, DevilRobber can also steal the user’s existing Bitcoin wallet if it finds the appropriate files.

Sophos suggests users be aware of signs that point to a malware attack. For example, a malware attack can result in the slowdown of overall computing performance, with affected users reporting sluggishness as the Trojan steals GPU resources for mining purposes.

In order to avoid unwanted DevilRobber installations, Mac users are advised to refrain from downloading software via untrusted sources, even if they appear to be legitimate. It is not known at this time whether other Mac applications available on torrent sites come bundled with the new Trojan horse.

Apple has yet to acknowledge the new threat, though common anti-virus programs are able to detect DevilRobber.

The new malware is the most recent in a wave of programs targeting an increasing number of Mac owners. Apple recently cleared a threat from a non-functional Chinese Trojan horse that disguised itself as a PDF download.

Recently various instances of a different, more advanced malware program emerged. “Flashback” posed as an Adobe Flash installer, with a later upgraded version programmed to disable the default OS X anti-malware protection thus leaving systems vulnerable to subsequent attacks.
